Parra, 33, spent three of his first four seasons as a starter with the Milwaukee Brewers, but he struggled mightily with a 5.13 ERA over 454.1 innings, which forced him to the minors in 2011 and a role in the bullpen upon his return the following year.

He spent the past three seasons with the Cincinnati Reds, making 40 appearances with a 3.90 ERA in 2015. Over the course of his eight-year career, Parra has been lit up by right-handed batters, which has been a huge pitfall:

Parra has also struggled with wild pitches, leading the league with 17 in 2008. Here is a look at one during the opening series at Busch Stadium against the St. Louis Cardinals in 2013:

The Cubs already have a slew of left-handed relievers competing in camp, slimming Parra’s chances of making the big league team. In addition to those already on the 40-man roster—Travis Wood, Clayton Richard and Rex Brothers—the Cubs also have Jack Leathersich and Edgar Olmos competing this spring, according to Steve Adams of MLB Trade Rumors.

Parra’s signing is a win for the Cubs, who at the very worst get an inexpensive option who adds depth to their relief corps as a minor league option.
